Monitoring and Analyzing Switch Operation
Traffic Mirroring
VLAN Interface with Traffic Direction as the Selection Criteria. Use
this command when the direction of traffic movement on a specific VLAN
interface defines the criteria for mirroring traffic.
:
Syntax: vlan < vid-# > monitor all < in | out | both > mirror < 1 - 4 | name-str >
[< 1 - 4 | name-str > < 1 - 4 | name-str > < 1 - 4 | name-str >]
This command assigns a mirroring source to a previously
configured mirroring session on a source switch. It specifies the
VLAN source to use, the direction of traffic to mirror, and the
session identifier.
Assigning a VLAN to a mirroring session precludes assigning
any other mirroring sources to the same session. If a VLAN is
already assigned to a given mirroring session, using this
command to assign another VLAN to the same mirroring session
results in the second assignment replacing the first. Also, if there
are other (port, trunk, or mesh) mirroring sources already
assigned to a session, the switch displays a message similar to:
Mirror source port exists on session N . Can not
add mirror source VLAN.
The no form of the command removes a mirroring source
assigned to the session, but does not remove the session itself.
This enables you to repurpose a session by removing an
unwanted mirroring source and adding another in its place.
vlan < vid-# >:
Identifies the VLAN on which to mirror traffic.
monitor all < in | out | both >:
Uses the traffic’s direction of
movement on the specified
vid-#
to select traffic to mirror.
Refer to the syntax description on page B-48. (Using
monitor
without mirroring criteria or session number affects
session 1. Refer to “Monitor Command” on page B-71.)
mirror < 1 - 4 | < name-str > :
Assigns the traffic defined by the
interface and direction to a session, by number or (if
configured) by name. (The session must have been
previously configured. Refer to “3. Configure the Mirroring
Session on the Source Switch” on page B-43.) Depending on
how many sessions are already configured on the switch,
you can use the same command to assign the specified
source to up to four numeric or alphanumeric identifiers.
For example,
1 2 4
. For limits on configuring mirroring
sources to a given session, refer to “Mirroring Source
Limits” on page B-47.
< 1 - 4 >
: Assigns a numeric session identifier to
associate with the traffic selected for mirroring.
